Get the connected Wi-Fi network SSID on iOS (in Swift).

WiFiSsid.swift

import Foundation
import SystemConfiguration.CaptiveNetwork

func getWiFiSsid() -> String? {
    var ssid: String?
    if let interfaces = CNCopySupportedInterfaces() as NSArray? {
        for interface in interfaces {
            if let interfaceInfo = CNCopyCurrentNetworkInfo(interface as! CFString) as NSDictionary? {
                ssid = interfaceInfo[kCNNetworkInfoKeySSID as String] as? String
                break
            }
        }
    }
    return ssid
}

works fine for an iOS App, but when I use this code in an MacOSX App, Xcode says that CNCopyCurrentNetworkInfo is unavailable. What is the reason for this?

@Martius108 Unfortunately, CNCopyCurrentNetworkInfo function is available on iOS only. For macOS you need to find other way to get info about the connected Wi-Fi network.

What other information could I get from this apart from the ssid?

hey i am currently developing ios apps on virtual machine so the SSID is nil
is that should be tested on i phone or what ??

Im trying in iOS 12 with physical device and it happens to me like @mohamedzead1996. iOS 12 bug?

@MRodSebastian On iOS 12 I got nil first, but after turning on the new "Access WiFi Information" in Capabilities is working fine.

Does this capability is required for iOS 12 or Xcode 10? I mean, will it work on iOS12 if we build using Xcode 9 and submit app to AppStore?

Thanks, @MihaiPantiru! That worked great for me.

@MihaiPantiru thanks! That solved my problem.
@shivareddy It's required for Xcode 10, since it works fine before I update to Xcode 10.

Thank you, @MihaiPantiru that solved the problem, when I updated to Xcode 10, iOS12.

I have issue "does not support the Access WiFi Information capability". How to fix it ? @MihaiPantiru

A little tidy up.

extension UIDevice {
    @objc var WiFiSSID: String? {
        guard let interfaces = CNCopySupportedInterfaces() as? [String] else { return nil }
        let key = kCNNetworkInfoKeySSID as String
        for interface in interfaces {
            guard let interfaceInfo = CNCopyCurrentNetworkInfo(interface as CFString) as NSDictionary? else { continue }
            return interfaceInfo[key] as? String
        }
        return nil
    }
}

Not work for iOS 13 anymore

Is their any valid way to get SSID in iOS 13?

of course, https://github.com/HackingGate/iOS13-WiFi-Info

Even with the core location authorisations and the wifi capability, I'm not able to retrieve the SSID via the CNCopyCurrentNetworkInfo (as reported here: https://github.com/HackingGate/iOS13-WiFi-Info)
Did anyone get the same problem?

I got the sample problem @AlexFlyce. After I upgrade iOS13 and XCode 11.1, CNCopyCurrentNetworkInfo return NULL. It haven't any problem before my upgrade. Did anyone have solve the problem ?

Apparently it's a known issue from Apple side, and the best we can do is to submit more logs of the bug. (PS: If you reboot your phone, the bug won't appear anymore, so it's not even easy to reproduce at that point)
My biggest problem is that my app relies completely on this, and I'm getting bad reviews...

After installing the 13.3 GM release, I was able to get the command to working.

I was also able to get the FGRoute pod to work fine except for the FGRoute.getSSIDDATA() function as it's causing my application to crash, although I don't need that function.
